Re: SAN Disks not appearing
vgexport the volume groups with the map files.
Then vgimport it with the correct device files.
You do not want to specify the device files then while you vgexport the volume groups use the -s option.
Then again while vgimporting again use the -s option

Re: SAN Disks not appearing
What version of hp-ux are you using? The procedure below if for 11.23 and earlier. Check to see if you are using 11.31.
This is a complicated task but there are several ways to verify your work.
a) vgcfgrestore -f /etc/lvmconf -l
What you should see are the old devices
b) vgscan -s -a -v -p
-p for preview
-a for search every controller
-v for verbose
-s for sharable pvs - causes vgscan to read the lvm header of every pv, note the vg written in the lvm header, populate /etc/lvmtab by this info.
c) vgexport -p -v -s -m mapfile /dev/vg
-p preview
-v verbose
-s sharable - update the pv lvm header by vg belonging to the pv
-m hp-ux ascii file, used to rebuilt the vg.
d) vgimport -s -p -m mapfile /dev/vg
-p preview
-m mapfile
-s sharable - add pv's based upon lvm header
here is a good thread.
